After a lunch break Friday in his murder trial, 23-year-old Derrick Loving decided to change his plea from not guilty to guilty. Now he waits through the weekend to learn his fate. Commonwealths attorney Charles Orange may have one more witness when the trial resumes at 8:30 a.m. Monday, and the defense is expecting to take an hour to an hour and a half before the jury can consider sentencing. Loving was on trial for the murder of sisters Hanna and Jessica Key. The Hopkinsville man was accused of first shooting Jessica Key, 18, and then his estranged girlfriend, Hanna Key, 22, outside Hanna Keys Russellville home at 463 E. Sixth St. during the early morning hours of Dec. 7. Both Keys had been standout athletes in basketball and track and field at Russellville High School. When Logan Circuit Court Judge Tyler Gill asked Loving why he shot Jessica Key, he said she spit in his face and they were arguing. Hanna Key was charging at him, and Loving said he thought she was going to kill him. I thought she had a gun, Loving said. Gill asked Loving what he was thinking when he shot Hanna Key. I wasnt thinking, he said. The Key family thought all along that Loving intended to kill Hanna and Jessica Key when he fired the gun, said Oscar Key, Hanna and Jessicas brother. His admission helps sew up a little bit of the wound, Oscar Key said. These situations are never happy, he said. The Key family lost two people dear to them and Lovings family will lose him also. It truly is a tragic situation, Oscar Key said. We dont hate Derrick at all. He said the Key family is disappointed more than anything. I feel sorry for him, Oscar Key said. I wish that there had been a different way to work out some of the differences. The jury will decide if Loving deserves a sentence of 20 to 50 years, 25 years to life, or life without parole. To impose either life or 25 years to life, the jury must find aggravating circumstances, such as previous convictions, multiple murders and creating a risk of death to several people in a public place. The jury also must weigh mitigating circumstances, including a lack of a significant criminal history, age of the defendant, the capacity to appreciate the criminality of the conduct, and if the act was committed while the defendant was under mental or emotional distress. Orange asked the jury to consider life without parole for both deaths. Defense attorney Chris Woodall asked for a sentence of a number of years instead of life. He said Loving decided to plead guilty to cut the trial short. He didnt want to live it again, didnt want the Key family to live it again, didnt want his family to live it again, Woodall said. Orange called Scott Doyle, a firearms and tool-mark examiner with the Kentucky State Police, to testify about the gun and bullets used in the murders. He said the bullets used did come from the gun recovered. Angela Weatherton, who works in the state medical examiners office, testified about the autopsies of the Hanna and Jessica Key. Hanna Key had two gunshot wounds one in the neck and the other in her thigh. The bullet that entered her neck ended in the spinal column, severing the spinal cord, Weatherton said. The bullet in her thigh injured muscles. Jessica Key also had two gunshot wounds, one just below her clavicle and the second just below her rib cage. The first bullet fractured a rib and ripped through a lung, her aorta and her esophagus. The second injured her liver and small intestine. Clifford Jackson, who lived next door to Hanna Key, said he was in his bedroom working on his computer when he heard the first two shots. He then went to his front door to see what was going on. Jackson said he saw a vehicle pull out of Hanna Keys driveway and stop. Then he heard two more shots and the vehicle pulled in front of his house. Jackson said the driver opened his door and yelled to Jackson, Call the police, man. Call the police. Amanda Johnson and Victoria Gatewood each said they heard Loving say if he couldnt have Hanna Key, no one would because he would kill her. The conversation took place in front of Gatewoods home a couple of weeks before the shootings. Orange next called on members of the Key family, including Brenda Key, mother of the sisters. Orange asked Brenda Key how the loss of her daughters has affected her family. Its devastating to us all, she said. Brenda Key is raising Hanna Keys two children, Jamal and Jasmine. She said 3-year-old Jamal still has some memories of his mother. Jasmine will never have a memory of her mother, Brenda Key said. Jasmine is 13 months old and Loving is her father. Hanna and Jessica Keys father, William Key, said he talked with his daughters a lot. They were my best friends, he said. Not a day goes by that I dont have a cloudy day. Ill never, ever get over this feeling. During the morning session, Orange showed the jury a taped statement from Loving taken hours after the shooting deaths of Hanna and Jessica Key. Loving said Jessica Key called him names and spit on him after he got out of Hanna Keys car. When she spit, I shot her, Loving said of Jessica Key. Jessica Key provoked him, Loving said. I guess I just lost it, he said. Loving said he shot Jessica Key twice, then Hanna Key came at him and said she would kill him. Then, he shot Hanna Key and she fell against her car. He didnt remember how many times he shot her. Russellville Police Detective Kenneth Edmonds interviewed Loving on the tape and spent most of the morning and afternoon on the stand. On the tape, Loving said he and Hanna Key were in the car when she told him to get out. She pulled out a gun from under her seat. She pointed it at me but it had the safety on, Loving said. When Jessica Key pulled up, Loving took the gun from Hanna Key. He said she told him she wasnt going to use it. Hanna Key got out of the car first, then the altercation with Jessica Key and the shootings occurred. Loving got into his truck and left the scene, stopping long enough to tell a neighbor to call the police. As he was driving out of town, Loving saw police cars coming toward him and he threw the gun out the window. I was nervous, he said. I just threw it. Loving said he and Hanna Key never fought before. I told her everything, she told me everything, he said. The two had planned to be married, though their relationship was rocky near the end. Earlier in the day, Edmonds said he received the call at home at about 1:25 a.m. Dec. 7. He went to the police department to pick up equipment, and then headed to the scene. Officer Ron Mills told Edmonds what he knew about the situation. He was also given a description of a vehicle seen leaving the scene. Edmonds said he knew Hanna Key was dating a man who drove a vehicle fitting that description. Edmonds went to the hospital to try to talk to the Key sisters. He was told they were dead upon arrival. Edmonds went to Brenda Keys home and informed her the sisters were dead. Edmonds said he went back to the crime scene to process the scene. He took photographs of the scene and collected evidence including the blood and shell casings. As he was heading back to the office, two men flagged him down and told him about a gun that was lying on the viaduct on U.S. 68/Ky. 80 heading out of Russellville toward Hopkinsville. Photos were taken and the gun was taken into evidence, Edmonds said. It was covered in frost and had three live rounds in it, Edmonds said. Two rounds were in the clip and one was in the chamber. Edmonds called Hopkinsville police and let them know who he was looking for, then went to Hopkinsville where he talked to Lovings aunt and mother. Edmonds then returned to Russellville and was in his office taking care of some paperwork when Loving called from his mothers house. He said he would turn himself in to me and no one else, Edmonds said. Edmonds brought Loving back to Russellville where he interviewed him on camera. Edmonds returned to the scene routinely over the next few days looking for the two missing shell casings. On Dec. 9, Edmonds found two shell casings in the yard near Hanna Keys vehicle. Russellville police officer Victor Shifflett began the day by telling the jury about his involvement in the investigation. He sketched the crime scene with the assistance of officer Ron Mills. The officers measured the crime scene and sketched the evidence found, including the two shell casings and blood. There was a three-foot pool of blood in the area where Hanna Key fell, Shifflett said. Shifflett also attended the autopsies of the two sisters in Louisville. He took bullets removed from the bodies and put them into a box. Bullets were removed from Jessica Keys upper back and left-side torso and from Hanna Keys spine and back. Shifflett took pictures of the removal of the bullets. On cross-examination, Shifflett said he gave the medical examiner some background on what the officers thought happened to the sisters. Shifflett said he didnt sketch any footprints because of the medical personnel and police officers who had been in the area. It would have been impossible to distinguish whose was whose, especially in the low light we had, Shifflett said. A metal detector failed to find the other two shell casings, Shifflett said. The house had just been roofed and several roofing nails and other debris were found.
